No not really usually a month goes by fast an then 4-5 days (pending how many days in the previous month) also goes by fast. so it is not as long as you may think.
That depends on what you'd call a 'day' on the sun. If a day is one cycle of light and dark ... like it is for everything else in the solar system ... then there's no such thing on the sun. The sun...
Well in spring day is about 23 hr. long and night is only 1hr. because when the Earth faces the sun it moves slower and when night comes it gets faster.
